How to call EJB deployed on OC4J from java stored procedure?

Hello,
I'd like to call EJB from java stored procedure. My example works fine from command line, but the problem seems to be with deployment of this code into database. Especialy I'm wondering how to reference jars like oc4jclient.jar, ejb.jar, ... from java stored procedure.
Is there some example how to do that ?
Can You help me please ?
Many thanks,

What I did to solve this problem was to
create a simple RMI remote object that
resides outside the database JVM and that
serves as a proxy EJB client for your java
stored procedure. The stored procedure can
invoke a method on the remote RMI object
which then looks up the EJBean's home
interface and invokes the relevant method on
the bean's remote interface, and relays any
return values back to the java stored
procedure.
Hope this helps,

How to lookup EJBs deployed in OC4J from a standalone client application

Hello all,
I am trying to lookup an EJB deployed in OC4J 10.1.3 from a standalone client application using the following code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://localhost:23791");
env.put(Context.SECURITY_PRINCIPAL, "jazn.com/test");
env.put(Context.SECURITY_CREDENTIALS, "test");
Context context = new InitialContext(env);
Object ref = context.lookup("ejb/Dispatch");
I get the following error:
javax.naming.NameNotFoundException: ejb/Dispatch not found
     at com.evermind.server.rmi.RMIClientContext.lookup(RMIClientContext.java:51)
     at javax.naming.InitialContext.lookup(InitialContext.java:347)
For the lookup string I've also tried:
"java:comp/env/ejb/Dispatch" and "Dispatch"
For the Context.PROVIDER_URL property I've also tried:
opmn:ormi://localhost:6003:instance
The result is always the same.
I appreciate if someone could help me with this?
Thanks,
Georgi

Georgi,
Your question has been discussed many times on this forum. Search the forum archives for "RMIInitialContextFactory".
The PROVIDER_URL needs to include the name of the deployed application that your EJB is part of, for example:
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/MyApp");The lookup name has to be the value of the "ejb-name" element in your "ejb-jar.xml" descriptor file.
Your SECURITY_PRINCIPAL value looks strange to me. Personally, I use "principals" (and not JAZN), so I modified the "application.xml" file (in the "j2ee/home/config" subdirectory) to use "principals". Look for the following comment in that file:
Good Luck,
Avi.

How to call a Asynchronous bpel process from a PLSQL procedure?

How to call a Asynchronous bpel process from a PLSQL procedure?

Hi,
You could do something smart and technical very spiffy with soap-stacks in the database and/or dbms_ws/dbms_http. But I allways find AQ with AQ-adapter the simplest. Let Pl/sql enqueue a message on an aq-queue and subscribe an aq-adapter process on it. That can call your async-bpel process. If you want to get answer back in pl/sql, let the aq-adapter process enqueue a response message on another queue or on the same queue with another consumer name. Give it a correlation-id that you provided in the payload of your request message. Your pl/sql process can then do a dequeue on that correlation-id. It will sit and wait until a message with that correlation id is enqueued on the queue.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

Return national language strings from java stored procedures

Hi, all.
How does i can return String which contains national characters from java stored procedure? I.e. convert UTF java string to national language of database. It's does not processing automatically (why?).
declaration of procedure:
CREATE OR REPLACE FUNCTION TestNLSString RETURN VARCHAR2
AS
LANGUAGE JAVA
NAME 'test.SomeClass.getNLSString() return java.lang.String';
SELECT TestNLSString AS X FROM DUAL;

OS: Windows 2000 Server
Oracle Server version: Oracle 8.1.7.1.4

Ok. I had a specific problem.
I want to use java stored procedure (function) to make a connection to remote db using supplied connection parameters make some quieries there end return results in a form of structured data - object.
I have defined an object type in a database where the function will reside. I granted execute privilege to public user on this type, made public synonyms to both, the object type and the function, so anybody connected to the same database would have an access to this functionality.
I supposed that if I supply connection parameters for some other user but the same database when running the function, everything should go smooth. Yeah.
My java code executed ok: it made a connection to the db with some x user, it resolved object type descriptor given (oracle.sql.StructDescriptor), but pl/sql wrapper function reported the error I've mentioned. If I executed the function giving it the connection parameters for same account as where object type was declared, everything went fine.
My final solution is:
Make TWO! connection in java code: 1st for ("jdbc:default:connection:"), 2nd for remote database account.
Use first connection to construct oracle.sql.StructDescriptor
Use second connection to retreive data from remote db

Calling an EJB deployed in OC4J from a Java Stored Procedure

Hi all,
Well, I've been trying to figure this out for a bit now and haven't come up with a solution.
I have a Java Stored Procedure in a 9i database and would like to call an EJB deployed in the OC4J Container but DO NOT want to load the various Orion JAR files into the database.
I get hung up on the JNDI piece.
Has anyone figured out how to do this?
Got some code?
Thanks!

Doug,
This is not possible in Oracle9i Release1. in the upcoming Oracle9i DB R2, we will support loading a client-side jars of oc4j (oc4jclient.jar) in the database and call-out EJBs in 9iAS

How to execute a procedure or function from Java Stored procedure

Hi,
I am new to Java Stored Procedures. I am working on Oracle 8i and JVM 1.3.1. I want to call a PL/SQL procedure from within Java. I have tried looking at severa; cources but they are quite high level for me. Can someone provide a simple example including the Source Code for .java file and also the calling function's code?
Heres a sample of what I have been working on: I an including Java code, and Function code and how I call the function. Instead of doing "select sysdate from dual" I want to do like "create table temp1(var1 varchar2(10))" or similar... like "exec procname(var1)" etc.
Thanks in advance.
PS. The variable passed in function is just a dummy variable.

I have an After Submit Page Process that calls a stored procedure. In the exception section I'm using dbms_output.putline to display an error message, but the error message is not displayed in APEX. How can I have the error message generated from the stored procedure display in APEX?
Thanks so much.

Hi Apex_Noob,
I created On Load - Before Header process that uses apex_application.g_notification := :P3_ROLE;I'm sorry but I'm not sure what you mean by "instead of using dbms_output.putline use :P1_ITEM"
I have the following code in my stored procedure

How to get an updatable ADODB Recordset from a Stored Procedure?

In VB6 I have this code to get a disconnected ADODB Recordset from a Oracle 9i database (the Oracle Client is 10g):
Dim conSQL As ADODB.Connection
Dim comSQL As ADODB.Command
Dim recSQL As ADODB.Recordset
Set conSQL = New ADODB.Connection
With conSQL
.ConnectionString = "Provider=OraOLEDB.Oracle;Password=<pwd>;Persist Security Info=True;User ID=<uid>;Data Source=<dsn>"
.CursorLocation = adUseClientBatch
.Open
End With
Set comSQL = New ADODB.Command
With comSQL
.ActiveConnection = conSQL
.CommandType = adCmdStoredProc
.CommandText = "P_PARAM.GETALLPARAM"
.Properties("PLSQLRSet").Value = True
End With
Set recSQL = New ADODB.Recordset
With recSQL
Set .Source = comSQL
.CursorLocation = adUseClient
.CursorType = adOpenStatic
.LockType = adLockBatchOptimistic
.Open

The PL/SQL Procedure is returning a REF CURSOR like this:
PROCEDURE GetAllParam(op_PARAMRecCur IN OUT P_PARAM.PARAMRecCur)
IS
BEGIN
OPEN op_PARAMRecCur FOR
SELECT *
FROM PARAM
ORDER BY ANNPARAM DESC;
END GetAllParam;
When I try to update some values in the ADODB Recordset (still disconnected), I get the following error:
Err.Description: Multiple-step operation generated errors. Check each status value.
Err.Number: -2147217887 (80040E21)

The following properties on the Command object doesn't change anything:

I was having then same problem.
Finally, I've found how to "touch" the requierd bits.
Obviously, it's hardcore, but since some stupid at microsoft cannot understand the use of a disconnected recordset in the real world, there is no other choice.

How to get an UPDATABLE REF CURSOR from the STORED PROCEDURE

using C# with
ORACLE OLE DB version: 9.0.0.1
ADO version: 2.7
I returns a REF CURSOR from a stored procedure seems like:
type TCursor is ref cursor;
procedure test_out_cursor(p_Dummy in varchar, p_Cur out TCursor) is
begin
open p_Cur for select * from DUAL;
end;
I create an ADO Command object and set
cmd.Properties["IRowsetChange"].Value = true;
cmd.Properties["Updatability"].Value = 7;
cmd.Properties["PLSQLRSet"].Value = 1;
cmd.CommandText = "{CALL OXSYS.TEST.TEST_OUT_CURSOR(?)}";
and I use a Recordset object to open it:
rs.Open(cmd, Missing.Value,
ADODB.CursorTypeEnum.adOpenStatic,
ADODB.LockTypeEnum.adLockBatchOptimistic,
(int) ADODB.CommandTypeEnum.adCmdText +
(int) ADODB.ExecuteOptionEnum.adOptionUnspecified);
The rs can be opened but can NOT be updated!
I saved the recordset into a XML file and there's no
rs:baseschema/rs:basetable/rs:basecolumn
attributes for "s:AttributeType" element.
Any one have idea about this?
thanks very much

It is not possible through ADO/OLEDB.
Try ODP.NET currently in Beta, it is possible to update DataSet created with refcursors. You need to specify your custom SQL or SP to send update/insert/delete.
As I remember there is a sample with ODP.NET Beta 1 just doing this.

I then wrap this using the following function spec in pl/sql:
create or replace function callXMLP(input1 VARCHAR2, output1 VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.rtfToXsl(java.lang.String,java.lang.String) return java.lang.String';
and
create or replace function mergeXMLXSL(xml VARCHAR2, xsl VARCHAR2, output VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.mergeXmlXsl(java.lang.String,java.lang.String,java.lang.String) return java.lang.String';
Calling the callXMLP function works fine, and produces an XSL file from the input RTF file as expected.
When I run the mergeXMLXSL function, it says that the function has completed successfully, but it seems to be throwing an XDOException error as it is returning "Error - null" message from the Java.
A PDF document is being created, but it does not have any content. I have also modified the Java to create an RTF instead, but still the same thing happens.
Is there anything that I need to check, or something that I am missing when trying to create the final PDF document?
Please help, I am completely stuck with this now.
Many Thanks,

I needed to copy the XML Publisher fonts to the database server and ran the following java grants, note my $ORACLE_HOME is /opt/app/oracle/product/10.1.0/
